Basic knowledge of electric moped (1)

1. The selection of the method and style of the electric moped 1. The driving mode of the electric moped is generally selectedWheel hubThe drive is better, and the hub drive is better at the rear wheel drive, and the front drive is relatively poor. 2. For the placement of the battery, it is better to place the battery in a diagonal tube or a production tube in consideration of the balance of the vehicle and the convenience of getting on and off the vehicle. At present, the battery used is basically an economical lead-acid battery. As for the size of the battery, 36V12Ah batteries are basically used at present, and 24V electric vehicles are generally unpopular due to their short driving range. Functional style selection 1. Standard type: The motor power of this type of electric moped is generally 150W-180W, especially the shape is smooth, the continuous mileage is 40-50 kilometers, the operation is simple, the price is moderate, and the price is about 2400-2700 yuan. It is suitable for users who have a long commute distance and a certain degree of mobility in work and life. 2. Multi-function type: This type of electric vehicle generally adds front fork suspension, cushion suspension, and shock absorber to the standard type.HeadlampAnd other devices, it is characterized by more complete functions, more comfortable when riding, more convenient to use, the price is about 2700-3100 yuan. 2. What are the main technical performances of the complete electric moped? 1. Maximum speed: The maximum speed of the electric moped should not be 20KM/H. 2. Vehicle mass (weight): The vehicle mass (weight) of the electric moped should not be greater than 40KG. 3. Pedal driving ability: The electric power-assisted vehicle must have good pedaling ability, and the pedaling distance of 30 minutes should be no less than 7km. 4. Continued mileage: The continued mileage of the electric moped after one charge should be no less than 25km. 5. Maximum starting noise: When the electric moped is riding at a constant electric speed at the highest speed (electrically assisted riding at a speed of 15km/h～18km/h (Tempo)), the noise should be less than 62dB (A) ). 6. Electricity consumption per hundred kilometers: The electric power consumption of electric bicycles for electric riding (electrically assisted riding) should not be greater than 1.2kwh. 7. Motor power: The rated continuous output power of the motor of the electric booster should not be greater than 240kw.
